 printf -*s format string What's the difference between the following two format strings?
Here, it says "%-*s":
printf ("%s%-*s[%s]\n", prompt, 3, "", defvalue);
Here, it says "%*s":
printf ("%s%*s[%s]\n", prompt, 3, "", defvalue);
They both output the same.....

it means that the first printf puts the empty string to the left
of the 3 padding spaces, and the second printf puts the empty
string to the right of the 3 padding spaces.

Use spaces instead of tabs.

wide field. As the string passed to %s is an empty one you'll not
see any difference, try:
printf ("%s%-*s[%s]\n", prompt, 3, "x", defvalue);
and
printf ("%s%*s[%s]\n", prompt, 3, "x", defvalue);
and you'll probably recognize the difference.
